Blackjack card counting online doesn't work in RNG games, because the software shuffles before every hand and leaves nothing to track. This guide explains counting as history and theory, shows the Hi-Lo method with a worked example, covers why live dealer tables are a different question, and sets out what actually lowers the cost of playing blackjack online.
Online RNG blackjack reshuffles before every hand, so the count resets to zero each deal and counting has no effect.
Counting is a theory built for physical shoes dealt down over many hands; it's explained here as history, not a plan.
Reviewers report no live dealer games at Silver Oak, Planet 7, Royal Ace or Slot Madness, so counting has no target there either.
Basic strategy, low-edge versions and skipping side bets are what lower your cost; nothing removes the house edge.
Treat any software sold as an online card counter as a red flag.

Does blackjack card counting work online?
No, not in the RNG blackjack that online casinos mostly offer. A random number generator deals each hand from a freshly shuffled set of cards, so the cards from the last hand are back in play before the next one starts. Counting relies on knowing which cards have left the shoe, and in RNG blackjack none have.
That makes this page mostly history and theory. It's still worth understanding, because sellers of "online counting systems" rely on players not knowing why counting can't work there. If you're new to the game, start with how to play blackjack and the rest of our casino guides.
How card counting works in theory
In a physical shoe, cards come out and aren't replaced until the next shuffle. If many low cards have been dealt, the remaining cards are richer in 10s and aces. That slightly raises the chance of blackjacks, which pay 3:2, and of the dealer busting. A counter keeps a running tally to estimate that balance and bets more when it leans their way.
The best-known method is Hi-Lo, a balanced count where a full deck adds up to zero.

High cards leaving hurts the player
A card counting system doesn't predict the next card. It only estimates whether the remaining mix is slightly better or worse than average, and even a favorable count leaves the house ahead on many individual hands.
Running count and true count: a worked example
The running count is the plain total. The true count divides it by the number of decks still in the shoe, because a +4 matters far more with one deck left than with six.

Decks left: 5
True count = +2 ÷ 5
+0.4
A true count of +0.4 is close to neutral. Counters in physical games typically wait for much higher true counts before raising bets, which is why counting needs many hands, a deep shoe and a large bankroll to mean anything, and why losses during the long waits are normal.
Now apply this to RNG blackjack. After the hand, the software reshuffles. The next hand starts from a full set, the running count returns to zero, and the true count is always zero.
A short history of card counting
Card counting came out of mathematical work on blackjack in the middle of the last century, popularized by mathematician Edward Thorp's book Beat the Dealer. The same computer analysis produced basic strategy, the table of best plays that is still the most useful thing a blackjack player can learn.
Land casinos adapted over the following decades. Common responses included more decks per shoe, shuffling earlier (less of the shoe dealt, often called lower penetration), automatic shuffling machines that return cards continuously, and the right to refuse play or cap bets for players they suspect. Each change made the theory harder to use.
Online RNG blackjack is the end point of that trend. It behaves like a shuffle after every single hand, which is the condition under which counting provides no information at all.
Online card counting by game type
Whether counting has anything to work with depends on how the cards are handled. Here's how the main formats compare.
Live dealer games stream a real table, so in principle cards come from a physical shoe. In practice the studio sets the shuffle point and the rules, and you'd need to read them before assuming anything. Counting there is theory with many caveats, not a plan.
Search for card counting online and you'll find apps, courses and "systems" promising an edge over internet blackjack. Against RNG games, there's nothing for them to count. Treat these products as a warning sign, not a shortcut.
Any tool claiming to predict RNG blackjack cards is selling something the math rules out.
Claims of steady profit from online blackjack are false; the house edge applies to every hand.
Requests to install software that reads your screen or connects to your casino account put your account and data at risk.
Sites pushing a "method" alongside a casino link may be paid to sell you on playing more.
You can't remove the house edge, but you can avoid paying more than the minimum. Expected loss = total wagered × house edge, and the levers below change one side of that formula.

Whatever the rules on counting in a land casino, online RNG blackjack makes the question moot. The bigger legal question is whether online blackjack is allowed where you live. Seven states license real-money online casinos: New Jersey, Pennsylvania, Michigan, West Virginia, Delaware, Connecticut and Rhode Island. Maine legalized tribal-run online casinos in January 2026, but nothing had launched by October 2026 and a lawsuit is pending.
The partner casinos below are offshore and not licensed by any US state. Federal law (UIGEA) targets payment processing for unlawful internet gambling rather than making a bet a federal crime for the player, and state law decides what's allowed for you.

Frequently asked questions
Can you count cards in RTG online blackjack games?
Not in RNG blackjack. The software reshuffles before every hand, so no cards are ever removed from play and the count is always zero. Counting needs a physical shoe dealt down over many hands. Live dealer tables use real cards, but the studio sets the shuffle rules, and reviewers report no live dealer games at Silver Oak, Planet 7, Royal Ace or Slot Madness. Read how RNGs work for the detail.
What is the Hi-Lo card counting system?
It's the most widely taught counting method. Cards 2 to 6 count +1, 7 to 9 count 0, and 10s and aces count −1, and you keep a running total as cards are dealt. Dividing by decks remaining gives the true count. It's a theory for physical shoes and has no effect on RNG games. The card counting glossary entry gives a short definition.
Does card counting work on live dealer blackjack?
Only in theory, and usually not much. Live dealer games deal from a real shoe, but the studio decides how deep into the shoe it goes before shuffling, and early shuffles leave the count with little information. It's also irrelevant at most of our partner casinos, where reviewers report no live dealer games. See the live dealer guide for how these tables generally work.
Is online blackjack rigged if counting doesn't work?
No; counting not working is a feature of the shuffle, not proof of rigging. RNG blackjack is designed to make each hand independent, which is the same condition as a fresh deck every deal. Whether an offshore casino's software is fair is a separate question; RTG is the main provider at our partners. See are RTG games fair.
Should I buy software that counts cards online?
No. Against RNG blackjack there is nothing to count, so no software can give you an edge. Programs that read your screen or connect to your casino account can also risk your account and personal data. Treat such products as a red flag, and be wary of any site that pairs one with a casino sign-up link. Our casino myths guide covers similar claims.
What is the best strategy for online blackjack then?
Basic strategy, which gives the lowest house edge the rules allow. Add sensible habits: pick a version with a published high return, skip insurance and side bets, keep bets small relative to your budget, and decline bonuses that force heavy wagering. None of this makes blackjack profitable over time. The basic strategy guide has complete charts.
Who invented card counting?
Mathematician Edward Thorp is the name most associated with it, through his book Beat the Dealer, which used computer analysis of blackjack. The same work helped establish basic strategy. Casinos responded with more decks, earlier shuffles and shuffling machines, and online RNG games remove the opportunity entirely. Our how to play blackjack guide explains the rules counting was built on.
Can a casino close my account for card counting online?
Offshore casinos set their own terms and can close accounts under them, but counting isn't a realistic concern in RNG blackjack because it doesn't do anything. More common account problems involve bonus rules, duplicate accounts and verification. Read why casinos ask for documents and each casino's terms before you deposit, and keep copies of anything you agree to.
Does online blackjack use a new deck for every hand?
In effect, yes: RNG blackjack deals each hand from a freshly shuffled set of cards, so no card from the last hand is missing from the next one. That’s the reason card counting has nothing to track online. Every hand starts from a full deck or shoe, the running count resets to zero, and the true count stays at zero. Live dealer tables are different, because they deal from a real shoe with a shuffle point set by the studio. Our how RNGs work guide and RNG glossary entry explain the software side.
Can you count cards at Silver Oak or Planet 7 Casino?
No, card counting can’t work at Silver Oak or Planet 7, because both run RealTime Gaming blackjack on RNG software that reshuffles before each hand. Third-party reviews also report no live dealer games at either casino, which removes the only format where a real shoe is used. What you can control there is the version you pick, your bet size and whether you use basic strategy. Both are offshore and not licensed by any US state. See the Silver Oak review and the Planet 7 review for their games and terms.
How do you calculate the true count in blackjack?
Divide the running count by the number of decks still left in the shoe, and the result is the true count. A running count of +2 with five decks remaining gives a true count of +0.4, which is close to neutral; the same +2 with one deck left would be +2. Counters use the true count because a surplus of high cards matters more in a small remaining stack. In online RNG blackjack, the true count is always zero. The card counting glossary entry and shoe entry define the terms.
Do continuous shuffling machines stop card counting?
Yes, a continuous shuffling machine stops card counting, because used cards go straight back into the machine instead of piling up in a discard tray. The remaining mix never drifts far from a full shoe, so a count carries no useful information. Land casinos adopted these machines, along with more decks and earlier shuffles, as counting became better known. Online RNG blackjack goes one step further by shuffling before every hand. Our blackjack basic strategy guide covers the skill that still matters, and casino myths tackles other popular claims.
How much does online blackjack cost if card counting can’t help?
The cost is total wagered × house edge, and basic strategy keeps it as low as the rules allow. At the 99.6% return third-party listings report for RTG’s Super 21, 200 hands at $10 means $2,000 wagered and an expected loss of about $8. Side bets cost far more: Perfect Pairs is reported as low as 95.9%, so $500 there costs about $20.50 on average. Results swing widely in the short run. See house edge explained and the Super 21 game page for the numbers.
